Document Type and Number:
WIPO Patent Application WO/2018/199488
Kind Code:
A1
Abstract:
According to the present invention, a scroll compressor comprises: a first scroll including a first end plate part having a shaft receiving hole, through which a rotary shaft passes, formed in the center portion thereof, and having a discharge port formed around the shaft receiving hole, and a first wrap formed to protrude from one surface of the first end plate part; and a second scroll including a second end plate part having a rotary shaft coupling part formed in the center portion thereof such that the rotary shaft passing through the shaft receiving hole of the first scroll is eccentrically coupled thereto, and a second wrap formed to protrude from one surface of the second end plate part, and engaging with the first wrap so as to form a compression chamber with the same, wherein the first wrap is formed such that a limit range of a stiffness modulus, which is defined as a reciprocal obtained by dividing a wrap height by a wrap thickness and multiplying the value by a curvature radius of the first wrap, is 0.005 mm or more so as to restrain the wraps from deforming, thereby preventing friction loss and wear and enabling the breakage of the wraps to be prevented.
